VIILLIAIVE H. FULLINGTON, OF CLEVELAND. OHIO.

SWIVEL.

Application filed August 22, 1921. Serial No. 494,2?0.

To all 10/1012]. '17; may concern Be it known that 1, WILLIAM H. FULLING- Torn a citizen of the United States. residing at Qleveland in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Swivels, of which the following is a specification.

This invention relates to swivels or swivel hooks, andit is particularly useful in connection with swivel hooks used in rope making, where the rope in formation is connected to the swivel and is then revolved to twist the strands.

The object of the present invention is to provide an improved swivel hook characterized by very little friction, which is highly desirable in the operation above referred to and doubtless also in other situations. Accordingly ball, hearings are prorided tor the shanks of the attaching menihers. such the hook or eye.

(fine form of the invention is illustrated in the acronipanying drawings in which Fig. l. is a plan oi? the swivel. Fig. 2 is a longitudinal section thereot. F 3 section on the line 33 of Fig. 2.

Referring specifically to the drawings 6 indicates an outer cylinder or shell. made o'l metal, 7 is an eye for connecting one end of the swivel. and 8 is a hook for connecting the other end.

Each end of the cylinder hearing. and each hearing consists oi an outer ring" an inner riiig l0 and balls 11 l1 etween the tw rings. The outer ring 5;? seats or abuts against a. flange 12 upset or turned inwardly at the end of the cylinder 6. so that the hearing will not pull out ol' the cylinder. The inner ring 10 is rela- 6 contains a tively loose. The shank 13 of either the eye 7 or the hook 8 extends through the rings of the respectlve bearings. and is enlarged, shouldered, or headed behind the inner ring 10, as indicated at 1%, so that it will not pull through said ring.

his construction permits a free rotation between the parts 7 and 8, each being provided with a ball hearing which permits a very free spin desirable in rope twisting and elsewhere. The invention provides a swivel rci'narlnibly free from binding friction and successfully accomplishes the in tended purpose.

I claim:

A swivel comprising a cylinder open at each end. an outer bearing ring seated in each end of the cylinder. an inner hearing ring heside each outer ring. halls between the in ncr and outer rings respectively an attaching member having a shank projecting through the outer and inner rings at one end of the cylinder, the inner end of the shank being enlarged to engage behind the inner ring. and the outer end thereof ending in a ring, another shank projecting through the outer and inner rings at the other end oi the cylinder, the inner end of said shanlpheing enlarged to engage the inner ring and the outer end thereof terminating in a hook, and the ends of the cylinder being criuiprd ever to hold the working parts.
